The configuration of the authentication information input unit 23 and the input / output unit 37 (see FIG. 3) is optimized depending on whether or not various information is input as the instructor authentication information.

[2. Operation example of this key control system] Next,
The operation of this key control system will be described with reference to FIG. The figure is a flowchart showing the operation flow of the present key control system, focusing on the operation of the main device 1. As shown in the figure, the operation of this key control system is from S1 to S
It is composed of 14 steps.

First, the main control unit 32 of the main unit registers the personal authentication information input from the input / output unit 37 in the storage unit 36 (see FIG. 3 for both) (S1).

The personal authentication information is information for identifying the person to whom the locking / unlocking authority should be given. Here, the personal authentication information is known only to the person who has the locking / unlocking authority. It is assumed that it is a secret code (for example, an alphanumeric array of 8 consecutive characters) consisting of an array of numerical symbols.

As a concrete input method of personal authentication information,
Security service provider (person in the security company in the previous example) and recipient (resident in the facility subject to security in the previous example)
However, it may be input through the input / output unit 37, or data may be received from an external device such as the security device 2 through the public telephone line 4. The main device 1 registers the input personal authentication information in the storage unit 36 as a data table. Of course, there may be a plurality of people who register personal authentication information.

In the present embodiment, in addition to the above personal authentication information, a telephone number assigned to the security device 2 is also registered in the storage unit 36 in advance as sender telephone number information described later.

If there is a matter to be added / changed in the personal authentication information registered in S1, the procedure returns to S1 to perform re-registration, while if there is no matter to be added / changed, the registered personal authentication information is confirmed. Then, the process to proceed to the next step is performed (S
2).

Addition of personal authentication information in this step
The change is appropriately made not only when there is an error in the personal authentication information registered in S1, but also when it is desired to increase the number of registered people. Further, in the case where the personal authentication information is a personal identification code consisting of an array of numerical symbols, the personal authentication information may be changed / updated regularly in order to reduce the risk of the personal authentication information being stolen. preferable.

In the next step, the abnormality detecting unit 31 (see FIG. 3) of the main device 1 determines whether or not an abnormality in the facility to be monitored is detected (S3). As described above, the abnormality detection unit 3
If 1 is composed of various sensors, human body invasion, glass breakage, fire, etc. in the monitored facility will be automatically detected as an abnormality in the monitored facility. It is assumed that a person presses an emergency / emergency button provided as appropriate to cause the abnormality detection unit 31 to detect an abnormality.

The key control system continues the monitoring / standby operation by repeating the process of S3 until the abnormality detecting section 31 detects an abnormality.

If the abnormality detecting unit 31 determines that an abnormality has been detected, the process proceeds to the next step, and the main unit 1 sends the transmitting / receiving unit 35.
(See FIG. 3) and the public telephone line 4 (see FIG. 2) are issued to the security device 2 (S4).

At this time, the main control unit 32 of the main device 1 sets the value of the emergency flag stored in the storage unit 36 to 1 (S5). The emergency flag is 1, when the main device 1 is in an emergency.
It is a parameter for checking the current status by setting it to 0 in non-emergency situations. The value of the emergency flag can be used not only by the main device 1 as the confirmation information of the own device but also by being provided to the outside.

In response to this, the security device 2 (control unit 22, see FIG. 2) which has received the abnormality notification from the main device 1 causes the administrator (instructor) to input the instructor authentication information. Here, the instructor authentication information is information for confirming that the instructor on the monitoring device side is a previously registered person, and should match the personal authentication information. In the present embodiment, the instructor authentication information is assumed to be the same as the above-mentioned individual authentication information, for example, a personal identification code composed of an alphanumeric array of continuous 8 characters.

The administrator (instructor) uses the authentication information input section 23.
When the instructor authentication information is input through (see FIG. 2), the security device 2 (control section 22) causes the transmitting / receiving section 21 (see FIG. 2).
Also, a telephone call for transmitting the entered indicator authentication information to the main device 1 is performed through the public telephone line 4.

The main device 1 (transmission / reception section 35) is the security device 2
To receive a telephone call (S6).

In the next step, the authentication control unit 33 of the main unit 1 acquires the caller telephone number from the public telephone line 4 and determines whether it matches the telephone number assigned to the security device 2 registered in S1. It is determined whether or not (S7). If the result of the determination is that they do not match, that is, if the acquired caller's telephone number is not registered, line connection is not performed, assuming that the call is not from a legitimate security device 2 (instructor), If the acquired caller telephone number matches the registered telephone number, proceed to the next step.

In the next step, the authentication control unit 33 of the main unit 1 operates the transmitting / receiving unit 21 (see FIG. 2) and the public telephone line 4.
Through the above, the above-mentioned instructor authentication information is acquired from the security device 2, and the authentication is performed by comparing this with the individual authentication information registered in S1 (S8). In the present embodiment, it is determined whether or not the personal identification code transmitted from the security device 2 and the personal identification code registered in the storage unit 36 match.

However, as personal authentication information and instructor authentication information, voiceprint data, fingerprint data, retinal image data,
When face image data or the like is adopted, it is generally considered that the data transmitted from the security device 2 and the data registered in the storage unit 36 do not completely match, unlike the case of the above-described personal identification code. Therefore, the instructor may be authenticated by comparing both data within the allowable error range.

As a result of the authentication, if the personal authentication information and the instructor authentication information do not match (NG), the public telephone line 4 is disconnected, while if they match (OK), the authorized instructor sends a message. It is judged that it is the instruction of, and it advances to the next step.

In the next step, the main controller 3 of the main unit 1
2 receives a control instruction from the security device 2 by data transmission via the public telephone line 4, and determines and confirms whether this is an unlock instruction (S9).

As a result of the determination confirmation, if the control instruction is other than the unlock instruction, the other processing corresponds to the control instruction, while if it is the unlock instruction, the process proceeds to the next step. In the present embodiment, the security device 2 is described as giving an explicit control instruction, but the control command from the security device 2 may be implicit. For example, it is possible to equate an incoming call from the security device 2 or a reception of the instructor authentication information with an unlock instruction.

In the next step, the authentication information input unit 23 (and the main control unit 32) of the main device 1 determines whether or not the content of the emergency flag set in S5 is 1 (S10).
By confirming the content of the emergency flag in this step, it is possible to determine whether or not the unlock instruction is a valid one issued in response to the abnormality notification. That is, when an abnormality is reported, a confirmation flag indicating that the notification has been made is set, and by confirming the content of the confirmation flag when performing authentication, the notification is made even though the abnormality is not reported. The unlocking instruction can be excluded as inappropriate.

As a result of the above judgment, if the content of the emergency flag is 1 (YES), the process proceeds to the next step, while if the content of the emergency flag is other than 1 (NO), it is regarded as an inappropriate unlocking instruction. Then, the public telephone line 4 is disconnected.

In the next step, the control instructing unit 34 (and the main control unit 32) of the main device 1 has the key control devices 3a to 3c.
(See FIG. 2) is instructed to unlock each (S11). The control instruction unit 34 determines the key control devices 3a to 3a according to the content of the control instruction (unlocking instruction) received from the security device 2 in S9.
Unlock c individually or all at once.

In the next step, in response to the unlocking, the guard / emergency personnel who enter the site (the facility to be guarded) perform on-site response such as investigating the cause of the abnormality and rescue the person in the facility (S12). That is, in this step, the key control system (main device 1) performs a standby operation. The security staff resets the security mode by pressing a reset button appropriately provided on the main device 1 or its peripheral device at the time of site response. When the security mode is reset, various sensors and alarms are stopped, so that smooth site response can be performed.

In the next step, the main controller 3 of the main unit 1
2 determines whether the security mode has been reset (S13). If the security mode has not been reset,
Assuming that the on-site response is unprocessed, the main device 1 is S12.
On the other hand, if the security mode is reset while returning to the stand-by operation, it is considered that the site response has been processed, and the process proceeds to the next step.

In this embodiment, since the security mode reset information means that the site has already been dealt with, the reset information can be provided for other purposes. For example, by proving that on-site response was made by the reset information,
Allows exemption judgment from guards / rescue personnel.

In the final step, the main control unit 32 of the main unit 1 sets the value of the emergency flag stored in the storage unit 36 to 0 (meaning non-emergency), and the monitoring / control of S3. The process returns to the standby operation (S14).

According to the above operation, according to the present key control system, since the locking / unlocking authority should be given, the remote locking / unlocking is performed only by the registered instructor. It is possible to perform accurate and quick on-site unlocking while reducing the risk of.

In the above description, information transmission / reception between the main device 1 and the security device 2 is performed by the public telephone line 4, but the communication line for information transmission / reception may be any mobile telephone line or the Internet. Can be adopted.

If the operation of this key control system is expressed as a key control method, the abnormality information of the facility to be monitored is transmitted to the external device through the authentication information registration stage in which personal authentication information is registered in advance and the communication line. Receiving the indicator authentication information input to the external device and transmitted from the external device according to the abnormality notification stage and the transmitted abnormal information, and comparing this with the registered personal authentication information. Can be expressed as having an authentication stage for performing authentication and a key control stage for instructing the key control device to lock / unlock according to the authentication result.

The operation of this key control system and the above key control method are as follows: the main control unit 32 of the main device 1, the authentication control unit 33,
It can also be realized by a program (key control program) in which the control instruction unit 34 is executed.

Further, the key control program is executed by the main unit 1
It can be stored in a computer-readable recording medium such as the storage unit 36 (see FIG. 3). The key control program may be supplied by a program medium read by a drive device provided as an external storage device in addition to the storage unit 36.

The program medium is a recording medium which can be separated from the main body, and is a tape system such as a magnetic tape or a cassette tape, a magnetic disk such as a floppy (registered trademark) disk or a hard disk, or a CD-ROM /
Disc system of optical disc such as MO / MD / DVD, IC
